[texts]Radio Wave Propagation In The Presence Of A Tropospheric Duct - Dresp, M. R.
"A full-wave solution has been obtained for radio wave propagation in the presence of an elevated tropospheric layer. This analysis was performed as part of the CNI (Communication, Navigation, Identification) experimental program. The tropospheric layer is modeled as a trilinear refractive index profile with a sufficient lapse rate so as to result in an elevated duct. The analytical solutions give the received signal level for air-to-air propagation paths at UHF, the corresponding signal fading ...

Ionospheric Plasma Disturbances And Effects On Radio Waves by Lee, Min-Chang. "Ionospheric plasma heating experiments were conducted at Arecibo to investigate generation of ionospheric plasma bubbles, sheet-like ionospheric irregularities, Langmuir waves, upper hybrid waves, and ion Bernstein waves. This research has shed light on physics and effects of HF waves on naturally occurring ionospheric plasma turbulence." Digitized by The Defense Technical Information Center (DTIC).

[texts]Collection of Light From an Optical Fiber With a Numerical Aperture Greater Than One - NON
In an optical fiber having NA greater than 1, light may be internally reflected when it strikes the fiber end at a fiber-air interface. This problem may be overcome by modification of the fiber by reverse tapering the core. Light is redirected by the taper to strike the interface at an angle closer to normal. This allows light to exit the fiber end that would by internally reflected in an untapered fiber of NA greater than 1...
